Added for You - Choosing The Right PAT Testing and Tagging Equipment
Although I love my work, parts of my research and writing can be demanding. I am a natural nutritionist, specializing in preparing articles, e-books, and other written material that shows people, like you, on how to understand and use natural remedies.Being able to make a career by writing was in many ways a dream come true, but it also has a downside to it. For every minute of pure joy on writing what I like, there are times when I need to relax, be enter
In recent years, we have seen how almost all transactions can be made online. Given the ease that online transactions bring, more and more companies are jumping on the bandwagon to provide products and services over the Internet. In keeping with the times, securities exchanges have also taken the necessary steps to provide online or web trading services to investors. This has made it possible for more people to invest in stock markets as information on these types
The tests that are required to meet AS/NZ 3760: 2003 are as follows
· Polarity
· Insulation Resistance
· Earth Resistance
· Current Leakage
The AS/NZ 3760 states that the earth resistance of the appliance can be tested either:
1. With a current between 100-200mA this is called a earth continuity
2. With a current of 10A this is called a routine test or,
3. With a current of 25A this is called a earth bond test
Each of these three tests has their advantages
Earth Continuity
A low current test is ideals for pieces of equipment with functional or signal earths. This is a circuit that has the earth that is connected through the circuit board. These pieces of equipment are not very common but can be found on scientific equipment and high end audio equipment (can be found at film, TV and sound studios). The users of this equipment normal know that it is earthed this way.
A disadvantage of an earth continuity test is that it will still pass with only one strand of wire connected in the earth. This is not sufficient for carrying large fault current. And if someone was to touch external metal during such fault the person is likely to be electrocuted.
Routine Test
There is little advantage to a routine test. But often testers that only use this test will be smaller and lighter that a 25A test due to the small transformer. Earth Bond Test
High current tests are good to make sure that there is a good connection in the earthing conductor. If there is any less that five strands connected in the earth the test will fail. The disadvantage is with high current tests if the conductor is lightly corroded the appliance will still pass For simplicity we can place the test and tag equipment in one of three distinct categories. The following is a guide to the different types, and highlights features to look for.
Simple PASS/FAIL types
PASS/FAIL type testers give a simple pass or fail test result allowing no interpretation of the test data. Some of the tester on the market will only carry out insulation and earth continuity tests or has an additional accessory to perform a leakage test and as a result will not be able to test appliances with Surge protectors (this is because AS/NZ 3760 states that a insulation resistance test or earth leakage test must be performed. Appliances with surge protectors will fail an insulation resistance test as a result the only way to test these appliances is to perform a leaking test). If the tester can
Traditionally, many large service businesses, have focused narrowly on direct operational needs like order handling & invoicing, when designing their information architecture. This way they have developed account-centric data structures. A real Customer could have more than one accounts, the records of which were unlinked in the customer database. In this case, more than one Customer records, would exist for the same real Customer. This data model would not refle

Do you feel like one in a million at work – and not in a good way? When you run into your boss in the hallway, do you get the impression she isn’t sure who you are? Are the juicy projects always going to someone else?If you answered “yes” to any of these questions, you need to raise your work profile. Here are some tips to get you started.1. Listen more than you talk. If you offer an opinion, suggestion, comment or question at every opportunity, soon

"Dig your well before you're thirsty" is the title of a wonderful book by Harvey Mackay. It is smart advice for investing your money, "Save your money before you need it", or growing your business, "Market today for tomorrow".When times are tough some businesses stop marketing. They reason, 'No one is buying so why should I advertise?' The other time some businesses stop marketing is when they are selling like crazy. Again they figure - 'I can't handle

One of the newest phenomena’s on cable television has been the rise in popularity of televised poker tournaments. This has led to an increase in interest in poker games and the creation of even more poker rooms on the Internet. The competition for players among these poker rooms is fierce and now you can capitalize on this competition and make some money without playing poker. Simply sign up for a good online poker affiliate program. These programs allow you to ea
PASS/FAIL testers have the advantage of being easy to use but can have a limited practical use. Manual Recording PAT Testers Manual PAT testers give much more functionality than the simple PASS/FAIL testers. As well as the PASS/FAIL these tester will all so give numeric results. These testers have standard Insulation and Earth Continuity tests, and most also carry out an Earth Leakage.
Downloadable PAT Testers
For testing large amounts of equipment a testers that automates the process and has recording capabilities is more suitable. These testers are able to initiate a pre-programmed test sequence via a shortcut menu. Test data, including the overall PASS or FAIL result, is stored for downloading and most of can be connected to a test and tag printer to print test labels. These testers often have a bewildering amount of features.
